目的：高比例的跟腱病患者出现双侧症状，人类和动物研究显示双侧组织学变化与一个肌腱的过度使用/病理学相关。目前的研究检查肌腱结构的变化，评估半定量使用超声组织表征，在有症状和无症状的肌腱在单侧跟腱病患者相比，没有肌腱病史的人。设计：横断面病例对照研究。方法：参与者跟腱病（n = 21），不同的严重程度和长度的临床症状，和6名参与者没有肌腱病的历史被招募。使用超声组织表征扫描肌腱，其每0.2 mm捕获连续的横向超声图像并呈现三维图像。超声组织表征通过测量连续横向图像上回声模式的稳定性来量化肌腱结构。四个回声类型的歧视，并表示为百分比。结果：正常肌腱结构的比例在三组间有显著性差异（P < 0.01），其中有症状的肌腱包含最少的正常肌腱结构（有症状的79.5%，无症状的81.8%，对照组86.4%）。无症状的肌腱包含显着减少正常肌腱相比，控制肌腱（p = 0.008），这表明无症状的肌腱结构受损，尽管没有symptoms.Conclusions：无论是跟腱结构受损的患者与单侧跟腱病。未来的研究需要调查这些变化是否会增加出现症状的风险。(C)2014年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Objectives: A high proportion of Achilles tendinopathy patients develop bilateral symptoms with human and animal studies showing bilateral histological changes associated with overuse/pathology in one tendon. The current study examined changes in tendon structure, assessed semi-quantitatively using ultrasound tissue characterisation, in both the symptomatic and asymptomatic tendon in unilateral Achilles tendinopathy patients in comparison to individuals with no history of tendinopathy.Design: Cross-sectional case-control Study.Methods: Participants with Achilles tendinopathy (n = 21), with varying severity and length of clinical symptoms, and six participants with no history of tendinopathy were recruited. Tendons were scanned using ultrasound tissue characterisation, which captures contiguous transverse ultrasound images every 0.2 mm and renders a 3-dimensional image. Ultrasound tissue characterisation quantifies tendon structure by measuring the stability of echopattern over contiguous transverse images. Four echo-types were discriminated and expressed as a percentage. Antero-posterior diameter of all tendons was Measured.Results: Significant differences Were observed in the, proportion of normal tendon structure between all three group's (p < 0.01), with the symptomatic tendon containing the least amount of normal tendon structure (symptomatic - 79.5%, asymptomatic - 81.8%, control - 86.4%). The asymptomatic tendon contained significantly less normal tendon in comparison to the control tendon (p = 0.008), suggesting the asymptomatic tendon is structurally compromised despite the absence of symptoms.Conclusions: Both Achilles tendons are structurally compromised in patients with unilateral Achilles tendinopathy. Future studies need to investigate whether these changes increase the risk of developing symptoms. (C) 2014 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.
